To all whom t may concern.'

Be it known that I, WILLIAM C. BowLnN, a citizen of the United States ofAmerica, and a resident of Holyoke, in the county of Hampden and Stateof Massachusetts, have invented new and useful Improvements in Planes,of which the following is a specification.

My invention relates to improvements in planes and more especially tothe adjusting means for the plane-irons, and consists essentially of ahorizontally adjustable member to the forward end of which the planeironis secured, and an oblique locking member for said first-named member,together with such other parts and members as may be necessary ordesirable in order to render the plane which is equipped with the newadjusting means practicable, serviceable, and eflicient in everyrespect, the construction and arrangement of parts and members beingsuch that said horizontally adjustable member and said locking memberare readily accessible, all as hereinafter set forth.

The primary object of my invention is to provide a plane with adjustingmeans for the plane-iron, which means not only are simple inconstruction and operation, strong and durable and highly eflicient, butare readily accessible, so that theplane Vdoes not have to be taken downor any part thereof be removed, when it is desired to adjust saidplane-iron forward or backward, and can be most conveniently operated toobtain the results desired, the application of a screwdriver at twofreely conspicuous points being all that is required in order to makewhatever adjustment is desired at any time.

Another object is to construct the plane in such a manner that thesupporting member for theplane-iron is at all times held and guided in afixed path which lies in the central, longitudinal, vertical plane ofthe implement.

@ther objects and advantages will appear in the course of the followingdescription.

I attain the objects and secure the advantagesl of my invention by themeans illustrated in the accompanying drawings, in which- Y Figurel is alongitudinal, central, vertical section through a plane which embodies apractical form of my invention; Fig. 2, a rear endelevation of certainof the new elements, the view being taken on lines 2--2,

looking in the direction of the associated arrow, in Fig. 1, andtherefore being a cross section through the frame of the plane; Fig. 8,a-fragmentary detail in top vplan of the parts and members shown in thepreceding view, and, Fig. 4, a detail inv side elevation of the link.

Similar reference numeralsdesignate similar parts throughout the severalviews.

Although l have illustrated a complete plane, it will not be necessarytodescribe all of the parts thereof and their functions, but only thoseinto combination or close association with which means enter and towhich they directly relate.` I will first, therefore, point out ordescribe briefy the old elements in question.

rlhe `frame of the plane consists of a sole 1 and cheek pieces 8-3 asusual, and is provided with ordinary front and rear handles 4 and 5,respectively. 'A plane-iron or blade is represented at 6, and -astiffener therefor at 7, the two being fastened together by a screw 8.The sole 1 has therein a throat 9 for the cutting edge of the blade 6.There are also a clamp 10 which has a slot 11 therein, a lever 12 toadjust the blade 6 longitudinally, with a thumb-screw 13 therefor,and alever 14 with which to rock said blade and attached parts on theirpivot, such pivot consisting of a screw 15. Thereis a longitudinal slot16 -in the blade 6, and a longitudinal slot 17 in the stiffener 7. Thescrew the new adjusting 15 is received in the slots. 16 and 17 All these'parts and members are oldl and well known bothstructurally andfunctionally Passing now to the new features it will be observed thatthere is a saddle vr18 on which is mounted a frog the sole 1,upon 19.vThe saddle 18 is located between the handles 4 and 5 and extends fromcheek to cheek 8, and said saddle preferably has a central,longitudinal, raised portion 4which is exteriorly convex or. arcuate incross section. The lbottom of the frog .19 is shaped to fit and ride onthe upper surface of the saddle 18, and thus is affordedv a substantialsupport of suiicient` size lor 'area' to render said frog stable andprevent any sidewise or torsional movement on the part of the frog. frogis a downwardly and forwardly 1inclined proj ection 2O that bears at thebottom edge on the sole 1 behind or adjacent to the throat 9. Otherwisethis frog is similar to At the forward end ofthe 55 f binder 28 in full,also the screw 22. The

`through the medium :tal

corresponding members in other planes, and' the screws 13 and 15 aretapped into said frog in the usual manner.

By adjusting the frog 19 back and forth on the saddle 18 the cuttingedge of the blade 6 is shifted in the throat 9 in the manner and to theextent desired. By this means and in this manner the throat clearancemay be varied.

Slidingly arranged in a bore through the longitudinal center of thesaddle 18 is an adjusting rod or bar 21 which I term an adjuster. Theforward end of the adjuster 21 is beveled to correspond with theinclination of the inner or rear side of the frog projection 20, andsaid projection is rigidly secured lto such beveled end of said adjusterby means of a screw 22. Fastened securely to the rear protruding end ofthe adjuster 21, by means of ascrew 23, is a link 24.-. An adjustingscrew 25 is tapped into the back end of the saddle 18 at one side of theadjuster 21. The screw 25 has a head with an annular groove 26 thereinto receive the end of the link 241- that is opposite to that which isattached to the adjuster, such end being bifurcated, as shown at 27 inFig. 4l, to enter said groove. Obviously if the screw 25 be turnedinwardly the adjuster 21 with the frog 19 will be` carried forwardly, ofthe link 24 and the screw 23, and if said first-named screw be turnedoutwardly said adjuster with said frog will be carried rearwardly,through the same medium as before. The handle 5 is in the central,longitudinal plane of the implement, and the adjusting screw 25 is asu'liicient distance from one side of said plane to permit ascrew-driver to be applied to said screw without interference on thepart of said handle. In other words, the handle 5 forms no obstructionto the use of a screwdriver Iin'adjusting the screw 25 to advance orretract the adjuster 21.

Locking means for the adjuster 21 is required, and the same consists ofa binder inthe form of a screw 28 which is tapped into said adjusterfrom above. The head of the screw or'binder 28 is in the slots 16 and 17in the blade 6 and stilfener 7, and from said head the shank of saidscrew extends downwardlyV and rearwardly through the frog 19, and alongitudinal slot 29 in the top of the saddle 18, into the adjuster 21.The latter is broken away in Fig. 1 to show the slot 29 is covered bythe frog 19. The head of the binder 28 is accessible for a screwdriverthrough the slot 1l in the clamp 10. It follows, therefore, that thebinder can be readily tightened and loosened by means of a screw-driverapplied through the slot 11 I tothe'head of said binder.

when* the binder 28 is tightened a fora-,s the frog 19 on to the saddle18 and the adsaddle, an adjuster juster 21 against the top of thebore insaid Saddle for said adjuster, clamping the fixed and immovable saddlebetween said frog and adjuster or the two latter to the former, so thatthe adjuster with the frog and attached parts is held securely in place.Upon loosening the binder 28 the adjuster 21 can be moved freely towhatever extent may be necessary, since ample space for the movement ina direct line of said binder is provided by the slot 29. The binder alsoprevents or assists in preventing the adjuster from rotating on itsaxis, due to the fact vthat no movement sidewise of said binder ispermitted by the sides of the slot 29.

To adjust the blade 6 in the throat 9, yit is lirst necessary to loosenthe binder 28, and lthen the screw 25 is turned to advance or retractthe frog 19 to the desiredextent. l fter this the binder is retightened.

More or less change in matters `of size, shape, construction, andarrangement of some or all of the parts of the plane may be made withoutdeparting from the spirit of my invention or exceeding the scope' ofwhat is claimed.

What I claim as my invention, and desire to secure by Letters Patent,is-
